Description

Technical Field

[0001] The present invention relates to the technical field of welding auxiliary devices, and more specifically, it relates to a welding deformation prevention device for prefabricated building construction. Background Art

[0002] A prefabricated building refers to a building in which a large amount of on-site work in the traditional construction method is transferred to the factory. Building components and fittings are processed and manufactured in the factory and transported to the building construction site, and are assembled and installed on-site through reliable connection methods. Prefabricated buildings mainly include precast prefabricated concrete structures, steel structures, and modern wood structures. Because of their standardized design, factory production, assembly construction, information management, and intelligent application, they are representatives of modern industrial production methods.

[0003] During the processing of prefabricated buildings, welding operations need to be carried out on some steel structure fittings. During the welding process, due to the action of different temperature fields on the steel structure, welding deformation is likely to occur. Welding deformation includes shape change and size change. This kind of deformation is quite cumbersome and difficult to control during the later correction process.

Detailed implementation mode

[0029] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation mode of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0030] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0031] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation mode of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate or selectively mutually exclusive with other embodiments.

[0032] Embodiment 1 further illustrates a welding deformation prevention device for prefabricated building construction proposed by the present invention, including an assembled beam frame 100. There are sliding grooves 101 on both sides of the assembled beam frame 100. A pressing mechanism 200 is slidably connected in the sliding grooves 101. The pressing mechanisms 200 are symmetrically arranged on both sides of the assembled beam frame 100 and are distributed along the direction of the assembled beam frame 100. A positioning mechanism 300 for assisting in fixing the workpiece to be welded is provided in the pressing mechanism 200, and an auxiliary mechanism 400 for adjusting the fixing position is arranged in the positioning mechanism 300. As can be seen from Figures 1 to 5 it, multiple pressing mechanisms 200 are slidably connected in the sliding grooves 101. The pressing mechanisms 200 are symmetrically arranged on both sides of the assembled beam frame 100. By adjusting the position of the pressing mechanism 200 in the sliding groove 101, different positions of the workpiece to be welded can be fixed;

[0033] The pressing mechanism 200 includes a support member 201 arranged in the sliding grooves 101 on both sides. A driving member 202 is arranged on one side of the support member 201, and a pressing member 203 is arranged on one side of the support member 201. The driving member 202 and the pressing member 203 cooperate to press the workpiece to be welded. The positioning mechanism 300 includes an auxiliary member 301 arranged on the driving member 202. A movable member 302 is arranged on one side of the support member 201. The auxiliary member 301 and the movable member 302 cooperate. An adjusting member 303 is arranged in the movable member 302, and a positioning member 304 adapted to the shape of the workpiece to be welded is arranged in the adjusting member 303;

[0034] Since metal spare parts will deform during welding, affecting the working stability of the metal spare parts, and some spare parts are irregular in shape, it is difficult to fix the metal spare parts during welding. The present invention locks the upper end of the workpiece to be welded through the pressing mechanism 200, and at the same time, by setting the positioning mechanism 300, it adapts to accessories of different shapes. In this way, the pressing mechanism 200 and the positioning mechanism 300 have a wide range of applications, and the pressing mechanism 200 and the positioning mechanism 300 operate synchronously, achieving the effect of one driving multiple movements. Moreover, the positioning mechanism 300 adopts an adaptive structure on the abdomen of the workpiece to be welded, avoiding the deformation and bending of the web during the welding process and ensuring the welding quality of the workpiece to be welded;

[0035] The auxiliary mechanism 400 includes a telescopic member 401 arranged on one side of the support member 201. A limiting member 402 is arranged in the movable member 302. A fixing member 403 is arranged between the telescopic member 401 and the limiting member 402. The telescopic member 401 and the limiting member 402 cooperate to adjust the position of the fixing member 403, so as to lock different positions of the workpiece to be welded;

[0036] Moreover, by arranging the auxiliary mechanism 400 inside the pressing mechanism 200, the present invention achieves the effect of adjusting the position of the fixing member 403, thus being applicable to the correction and limitation of webs with different thicknesses, preventing the web from bending and deforming during the welding process. The position of the fixing member 403 is adjusted by the cooperation of the telescopic member 401 and the limiting member 402, so that the fixing member 403 can be adjusted according to the actual thickness of the web, ensuring that the fixing member 403 always abuts and presses against the side surface of the web, so that the web will not be deformed or bent during the welding process, thereby improving the quality of the welded member after welding. The pressing mechanism 200 and the positioning mechanism in the present invention are applicable to H-shaped members, I-shaped members and cylindrical members, with a wide range of applications;

[0037] The assembled beam frame 100 includes two assembled cross beams 102 on both sides. A slope 103 is arranged between the two ends of the two assembled cross beams 102. A positioning interval 104 is formed between the assembled cross beam 102 and the slope 103. A reinforcing frame 105 is arranged between the two assembled cross beams 102. The reinforcing frame 105 is distributed inside the positioning interval 104. Fixed blocks 106 are fixedly connected to the upper end surfaces of the two assembled cross beams 102 corresponding to each other. The fixed blocks 106 are distributed along the upper end surfaces of the assembled cross beams. A transmission shaft 107 is correspondingly arranged between the two groups of fixed blocks 106. The transmission shaft 107 is arranged directly above the assembled cross beam. There are two assembled cross beams 102. The slope 103 is fixedly connected to the two assembled cross beams 102 on both sides. A reinforcing frame 105 is arranged between the two assembled cross beams 102. In this way, the overall structural strength and stability of the assembled beam frame 100 are ensured. And by arranging a transmission shaft 107 inside the fixed block 106, it is convenient for the conveyor belt to transfer the workpiece to be welded onto the assembled cross beam 102. The design of the transmission shaft 107 can reduce the frictional resistance between the workpiece to be welded and the assembled cross beam 102;

[0038] Working principle: When the present invention is in use, first, the workpiece to be welded is moved to the position where the pressing mechanism 200 is located through the transmission shaft 107. Then, the upper end of the workpiece to be welded is locked by the pressing mechanism 200. At the same time, by arranging the positioning mechanism 300 to adapt to different-shaped fittings, the pressing mechanism 200 and the positioning mechanism 300 have a wide range of applications. And the pressing mechanism 200 and the positioning mechanism 300 operate synchronously to achieve the effect of one driving multiple movements. At the same time, the positioning mechanism 300 adopts an adaptive structure on the abdomen of the workpiece to be welded to avoid the deformation and bending of the web during the welding process, ensuring the welding quality of the workpiece to be welded. At the same time, the auxiliary mechanism 400 is arranged to clamp and limit the two sides of the web, so that the web is firmly clamped and limited between the two pressing wheels 403b arranged symmetrically on the left and right. The design of at least two groups of fixing members 403 in each pressing mechanism 200 can ensure that there are at least two pressing points between the pressing mechanism 200 and the web, thus ensuring the clamping force of the auxiliary mechanism 400 on the web of the workpiece to be welded.

[0039] Embodiment II

[0040] On the basis of Embodiment 1, the following technical features are added: The support member 201 includes a support plate 201a slidably connected to the two side chutes 101. One side of the support plate 201a is fixedly connected with a locking bolt 201b. The support plate 201a is fixed in the chute 101 through the locking bolt 201b. A vertical plate 201c is integrally formed on the upper end surface of the support plate 201a. A notch 201d is provided on one side of the vertical plate 201c. The driving member 202 includes a fixing plate 202a fixedly connected to one side of the vertical plate 201c. One end of the fixing plate 202a is provided with a cylinder 202b. The output end of the cylinder 202b penetrates through one end of the fixing plate 202a and is fixedly connected with a driving rod 202c. A driving seat 202d is fixedly connected to the upper end surface of the driving rod 202c. A slot 202e is integrally formed in the driving seat 202d. A driving shaft 202f is connected by bearing transmission in the slot 202e. The pressing member 203 includes a fixing portion 203a arranged in the notch 201d. Notches 203b are formed on both sides of the fixing portion 203a. Movable plates 203c are rotatably connected in the notches 203b on both sides. A pressing plate 203e is rotatably connected between the movable plates 203c on both sides. One end of the pressing plate 203e is fixedly connected to the driving shaft 202f. A pressing portion 203f is integrally formed at one end of the pressing plate 203e;

[0041] It can be seen from Figures 1 to 5 that a support plate 201a is slidably connected in the chute 101. The support plate 201a is of an L-shaped structure. The support plate 201a is fixed in the chute 101 through the locking bolt 201b. A vertical plate 201c is integrally formed on the upper end of the support plate 201a. The vertical plate 201c is fixedly connected with a cylinder 202b through a fixing plate 202a. The cylinder 202b is adjusted by an external controller. The cylinder 202b drives the driving seat 202d on the driving rod 202c to move upward. A driving shaft 202f is connected by bearing transmission in the driving seat 202d. A pressing plate 203e is fixedly connected to the driving shaft 202f. One end of the pressing plate 203e is fixedly connected to the driving shaft 202f. When the driving shaft 202f moves upward, it drives the pressing plate 203e to rotate on the driving seat 202d and the movable plate 203c, so that the pressing portion 203f on the pressing plate 203e fixes the workpiece to be welded;

[0042] Working principle: As can be seen from Embodiment 1, the workpiece to be welded is moved to the position where the pressing mechanism 200 is located through the transmission shaft 107. Then, the cylinder 202b is started through the external controller. The cylinder 202b drives the driving seat 202d on the driving rod 202c to move upward. At this time, one end of the pressing plate 203e is rotatably connected to the slot 202e through the driving shaft 202f. At this time, one end of the pressing plate 203e located in the slot 202e is tilted up. The pressing portion 203f on the pressing plate 203e locks the workpiece to be welded, thus completing the locking of the workpiece to be welded.

[0043] Embodiment 3

[0044] On the basis of Embodiment 2, the following technical features are added: The auxiliary member 301 includes a sliding hole 301a provided in the vertical plate 201c. An auxiliary plate 301b is fixedly connected to the outer wall of the driving rod 202c. The auxiliary plate 301b is slidably connected in the sliding hole 301a. An extrusion portion 301c is integrally formed on the side wall of the auxiliary plate 301b. The extrusion portion 301c has an inclined portion 301d. The movable members 302 are symmetrically fixedly connected to the telescopic rods 302a on the vertical plate 201c. One end of the telescopic rod 302a is fixedly connected with an arc plate 302b. A compression spring 302c is sleeved on the outer wall of the telescopic rod 302a. The compression spring 302c is a carbon spring with high strength and is convenient for daily work. One end of the compression spring 302c is fixedly connected to the outer wall of the arc plate 302b, and the other end of the compression spring 302c is fixedly connected to the outer wall of the vertical plate 201c. The inclined portion 301d is in cooperation with the corresponding arc plate 302b at one end;

[0045] It can be seen from Figures 6 to 8 that a long strip-shaped sliding hole 301a is formed on the outer wall of the auxiliary plate 301b, and an auxiliary plate 301b is integrally formed on the outer wall of the driving rod 202c. When the driving rod 202c moves upward, the auxiliary plate 301b on the driving rod 202c is driven to be slidably connected in the sliding hole 301a. And the structure of the auxiliary plate 301b is further defined in the present invention. An extrusion portion 301c is integrally formed on the side wall of the auxiliary plate 301b. The extrusion portion 301c has an inclined portion 301d. In this way, the upward extrusion force of the inclined portion 301d drives the arc plate 302b to deflect. And the arc plate 302b is connected to the outer wall of the vertical plate 201c through the telescopic rod 302a and the compression spring 302c, ensuring that the arc plate 302b returns to its original position after the extrusion force of the inclined portion 301d disappears;

[0046] The adjusting member 303 includes semi-circular grooves 303a symmetrically provided in the arc plate 302b. Corresponding arc grooves 303b are provided in the semi-circular grooves 303a. Arc strips 303c are slidably connected in the corresponding arc grooves 303b. A semi-circular plate 303d is fixedly connected to the outer wall of the arc strip 303c. The semi-circular plate 303d is movably connected in the corresponding semi-circular groove 303a. Corresponding installation grooves 303e are provided in the arc plate 302b. A fixed shaft 303f is fixedly connected in the installation groove 303e. A rotating plate 303g and a rotating plate 303h are rotatably connected to the outer wall of the fixed shaft 303f. The rotating plate 303g and the rotating plate 303h are correspondingly arranged on the outer wall of the arc plate 302b;

[0047] In order to adapt to different shapes of the workpieces to be welded, two sets of semi-circular grooves 303a are provided inside the arc-shaped plate 302b. Inside the two sets of semi-circular grooves 303a, a semi-circular plate 303d is rotatably connected through an arc-shaped strip 303c. The semi-circular plate 303d is limited within the installation groove 303e by a rotating plate 303g and a rotating plate 303h. In this way, when the semi-circular plate 303d contacts the workpiece to be welded, at this time, the semi-circular plate 303d rotates within the arc-shaped groove 303b. Thus, by adopting an adaptive structure, the device avoids the deformation and bending of the web during the welding process and ensures the welding quality of the workpiece to be welded.

[0048] The positioning member 304 includes a semi-circular groove 304a provided inside the semi-circular plate 303d. An arc-shaped groove 304b is provided inside the semi-circular groove 304a. An arc-shaped strip 304c is movably connected to the inner wall of the arc-shaped groove 304b. An arc-shaped opening 304d is provided on the arc-shaped strip 304c. A tension spring 304e is fixedly connected to the side wall of the arc-shaped opening 304d. The tension spring 304e is a carbon spring with high strength, which is convenient for daily work. One end of the tension spring 304e is fixedly connected to a stopper 304f. The stopper 304f is fixedly connected to the top end of the inner wall of the arc-shaped groove 304b. A semi-circular plate 304g is fixedly connected inside the arc-shaped strip 304c. Extrusion blocks 304h are fixedly connected to the semi-circular plate 304g in a distributed manner. The extrusion blocks 304h are made of soft rubber material.

[0049] As Figures 8 to 9 can be seen, the present invention further defines the structure of the semi-circular plate 303d. A semi-circular groove 304a is provided inside the semi-circular plate 303d. An arc-shaped strip 304c is movably connected to the semi-circular groove 304a through an arc-shaped groove 304b. The arc-shaped strip 304c is fixed to the top end of the inner wall of the arc-shaped groove 304b through a tension spring 304e and a stopper 304f. In this way, the semi-circular plate 304g rotates within the semi-circular groove 304a. As can be seen from the above, after the semi-circular plate 304g inside contacts the workpiece to be welded, the semi-circular plate 304g can operate along the shape of the workpiece to be welded until the workpiece to be welded is fixed.

[0050] Working principle: As can be seen from Embodiment 2, when the air cylinder 202b drives the driving rod 202c to move upward, at this time, the driving rod 202c drives the extrusion part 301c on the auxiliary plate 301b to move upward. The inclined part 301d on the extrusion part 301c contacts the arc-shaped plate 302b. Due to the extrusion force brought by the inclined part 301d, the arc-shaped plate 302b is driven to operate, and the tension spring 304e deforms. Then, the semi-circular plate 304g on the semi-circular plate 303d contacts the workpiece to be welded. The semi-circular plate 304g can operate along the shape of the workpiece to be welded until the workpiece to be welded is fixed. Thus, by adopting an adaptive structure, the device avoids the deformation and bending of the web during the welding process and ensures the welding quality of the workpiece to be welded.

[0051] Embodiment 4

[0052] On the basis of Embodiment 3, the following technical features are added: The telescopic member 401 includes telescopic sleeves 401a symmetrically and fixedly connected to the vertical plate 201c. A lead screw 401b is rotatably connected inside the two telescopic sleeves 401a. The lead screw 401b is rotatably connected inside the arc-shaped plate 302b. The protruding end of the telescopic sleeve 401a is fixedly installed with a motor 401c through a bolt. One end of the lead screw 401b passing through the telescopic sleeve 401a is fixedly connected to the output shaft of the motor 401c. The limiting member 402 includes thread sleeves 402a symmetrically threaded on the outer wall of the lead screw 401b. Limiting rods 402b are fixedly connected to both sides of the outer wall of the arc-shaped plate 302b. Limiting seats 402c are symmetrically and fixedly connected to the two limiting rods 402b. Both ends of the lead screw 401b are rotatably connected inside the limiting seats 402c through bearings. Limiting blocks 402d are symmetrically and slidably connected to the two limiting rods 402b respectively. A positioning plate 402e is fixedly connected between the adjacent thread sleeve 402a and the limiting block 402d. The fixing member 403 includes a hydraulic ejector rod 403a fixedly connected to the positioning plate 402e. One end of the hydraulic ejector rod 403a is fixedly connected with a pressing wheel 403b;

[0053] It can be seen from Figures 2 to 6 that on one side of the vertical plate 201c, telescopic sleeves 401a are symmetrically and fixedly connected. The telescopic sleeve 401a is of a telescopic structure, and the protruding ends of the two telescopic sleeves 401a are rotatably connected with a lead screw 401b. In this way, while the arc-shaped plate 302b moves, it drives the telescopic sleeve 401a to extend synchronously. The upper end surface of the protruding end of the telescopic sleeve 401a is fixedly connected with a motor 401c through a bolt. By starting the motor 401c through an external controller, the motor 401c drives the lead screw 401b to rotate inside the arc-shaped plate 302b. Limiting rods 402b are fixedly connected to both sides of the arc-shaped plate 302b. Limiting blocks 402d are slidably connected to the limiting rods 402b. A limiting seat 402c is fixedly connected between the adjacent thread sleeve 402a and the limiting block 402d. At this time, the limiting block 402d limits the rotation direction of the thread sleeve 402a, so that the thread sleeve 402a moves in the vertical direction on the lead screw 401b;

[0054] When further locking the workpiece to be welded, the design of the two pressing wheels 403b can clamp and limit both sides of the web, so that the web is firmly clamped and limited between the two pressing wheels 403b symmetrically arranged on the left and right. The design of at least two sets of fixing members 403 in each pressing mechanism 200 can ensure that there are at least two pressing points between the pressing mechanism 200 and the web, increasing the clamping force of the auxiliary mechanism 400 on the web;

[0055] Working principle: As can be seen from Embodiment 1, when fixing the workpiece to be welded, the hydraulic ejector rod 403a drives the pressing wheel 403b to assist in fixing the workpiece to be welded. Such a design can ensure that there are at least two pressing points between the pressing mechanism 200 and the web, increasing the clamping force of the auxiliary mechanism 400 on the web. Moreover, the device can also adjust the fixing position of the pressing wheel 403b in the vertical direction. Specifically, the external controller is used to start the motor 401c, and the motor 401c drives the lead screw 401b to rotate within the arc-shaped plate 302b. The limiting block 402d limits the rotation direction of the lead screw sleeve 402a, causing the position of the lead screw sleeve 402a to change in the vertical direction, thereby driving the position of the limiting seat 402c to be adjusted, and thus adjusting the position of the pressing wheel 403b.

[0056] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
